Method and device for controlling feed concentration of ore grinder

Abstract

The invention discloses a method and a device for controlling an ore feeding concentration of an ore grinding machine. The method comprises the following steps: obtaining current main shaft oil pressure and power of the ore grinding machine and determining a current oil pressure state and a current power state of the ore grinding machine according to an oil pressure numerical value range of the main shaft oil pressure and a power numerical value range of the power; as response to the condition that the ore grinding machine is at a high-oil-pressure state and a high-power state simultaneously and reducing the ore feeding concentration of the ore grinding machine; and as response to the condition that the ore grinding machine is at a low-oil-pressure state and a low-power state simultaneously and improving the ore feeding concentration of the ore grinding machine. According to the technical scheme provided by the invention, when the load state of the ore grinding machine is too high, the ore feeding concentration can be reduced so as to reduce the load of the ore grinding machine and crush mineral aggregates sufficiently, and when the load state of the ore grinding machine is too low, the ore feeding concentration is improved so that the yield and the efficiency of an ore grinding process are improved and the energy consumption of concentrates per tonnage is reduced.

Description

technical field [0001] The present application relates to the field of ore smelting control, in particular to a method and device for controlling the ore concentration of an ore grinder. Background technique [0002] In the production process of ore smelting, since the raw ore obtained from mining cannot meet the smelting requirements, it is necessary to process the raw ore first to obtain concentrates that meet the smelting requirements, and then use them in the smelting process. The beneficiation operation mainly includes crushing and screening of raw ore, grinding and grading, sorting, concentrate dehydration and other links. Among them, the grinding process is to crush the crushed ore to a suitable particle size, and provide the crushed minerals to the sorting process. During the grinding process, since the ore is crushed, the effective mineral components can be dissociated from the gangue, and different effective mineral components can be dissociated from each other. ...
